Feather M4 Express ATSAMD51 ATSAMD51 Cortex M4

This Feather is fast like a swift, smart like an owl, strong like a ox-bird (it’s half ox, half bird, OK?) This feather is powered by our new favorite chip, the ATSAMD51J19 – with its 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset. And best of all, it’s a Feather – so you know it will work with all our FeatherWings! What a great way to quickly get up and running.
The most exciting part of the Feather M4 is that while you can use it with the Arduino IDE – and it’s bonkers fast when you do, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can’t install software on. When you’re done, unplug the Feather and your code will go with you.
